Apple Unveils iOS 27 With Smarter Siri, On-Device AI and Journal App

Apple has officially released iOS 27, bringing one of the biggest changes to the iPhone experience in recent years. The update focuses heavily on artificial intelligence, with a redesigned Siri, more powerful on-device AI capabilities, improved Visual Intelligence, and a range of changes across Apple’s built-in apps.

But iOS 27 isn’t only about AI. Apple has also refined its Liquid Glass interface, improved performance, expanded safety controls, and introduced new tools designed to make everyday iPhone tasks faster and more personal.

Why New iOS Versions Can Slow iPhone Performance and How to Speed It Up

What Is New in iOS 27?

The biggest addition is Siri AI, a significantly more capable version of Siri. Instead of simply answering individual commands, Siri can maintain conversations, understand personal context, interact with apps, recognize what’s on your screen, and use broader web knowledge.

For example, you can ask Siri to find a specific email, message, photo, file, or link. Siri can also perform actions inside supported apps and answer questions about information currently displayed on your iPhone.

Apple has also introduced a standalone Siri app, giving users a dedicated place to start conversations and revisit previous interactions. Siri conversations can synchronize across Apple devices through iCloud.

More On-Device AI

iOS 27 expands Apple Intelligence throughout the operating system.

Visual Intelligence has moved into the Camera app, where a new Siri mode lets you point your camera at something and ask questions about it. You can use it for tasks such as understanding information, checking nutritional details, or calculating a restaurant bill from a receipt.

Photos also gets improved AI editing tools. The updated Clean Up feature is better at removing unwanted objects, while Extend can generate additional image content around the edges of a photo. A new Reframe capability can also change the composition of an image.

A More Personal Siri

Another major addition is Write with Siri. You can ask Siri to generate text, rewrite something, adjust its tone, or provide feedback while writing.

Apple has also added automatic grammar improvements alongside traditional spelling corrections. On supported devices, Siri can use your previous writing style from Messages and Mail to produce more personalized text.

Liquid Glass Gets More Customizable

Apple has refined the Liquid Glass design introduced previously. iOS 27 improves readability and gives users a new control that adjusts the appearance from ultra-clear to more heavily tinted.

This means users who find transparent interface elements distracting have more control over how their iPhone looks.

Faster iPhone Performance

Apple has also focused on speed. iOS 27 improves app launches, photo loading, AirDrop transfers, keyboard responsiveness, and connectivity transitions between Wi-Fi and cellular networks.

Importantly, many of these system-level improvements are available even on older iPhones that don’t support Apple Intelligence.

Which iPhones Support iOS 27?

iOS 27 runs on iPhone 11 and newer, including the second-generation iPhone SE and later. However, not every compatible iPhone gets every AI feature.

Apple Intelligence requires newer hardware, including the iPhone 15 Pro and Pro Max, iPhone 16 series, and newer supported models. Some of the most advanced on-device Siri capabilities require even newer hardware.

For users with compatible Apple Intelligence hardware, Siri is arguably the biggest reason to upgrade. For older supported iPhones, the performance, interface, accessibility, and system improvements still make iOS 27 a worthwhile update.
